Monochromatic Ambidextrous Minimalist Travel Quilt

I had a unique request (my favorite kind) to make a custom quilt for a custom van, perfect for road trips. It was too hard to choose between flying geese (triangles) and a big bold graphic X, so we decided that I would try to do both, one on the front, one on the back, like a mullet quilt, but with a party in the front and a different, but clearly related, party on the back.
